Scientists have now succeeded in making microchips which are able to work same like the human brain. These microchips are able to store and process data same like our brain. The researchers have termed this as the “holy grail of computer technology”.
Photonic microchips work like brain with a much faster response
In the University of Exeter, the research team of Professor C. David Wright used light, not electricity as their source of energy. They used photonic microchips of a computer to design the system. This works in the same way as the synapses of brain works.
The total research is published in the September 27th, 2017 edition of Science Advances. The team consists of researchers from the Oxford, Exeter, and Munster universities. They used common materials to combine the phase-changing material like reusable optical discs.
They designed a special type of integrated photonic circuits using these to give a brain-like synaptic response.
Another important part of this invention
The most important outcome of this research is these artificial synapses can work at a thousand times faster speed than that of a human brain. Scientists are now hoping to start a new era of computing where machines can actually think and work in the same way as our brain work. The machine response will be super fast and energy efficient.
According to the leader of the scientist team Professor Harish Bhaskaran of Oxford University, microchips, working in the same way as a human brain, have been the Holy Grail for scientists.
Using a complex network of neurons and synapses, a human brain can store, process and calculate immense data simultaneously. Many scientists have tried to mimic the functionality of the human brain.
According to the reports of Prof. C. David Wright, conventional electronics computers are pretty slow and trying to make them smarter can cause immense electricity consumption. Even they are unable to multitask by parallel processing simultaneously with inbuilt learning ability like a human brain.
The group of scientists has handled both the issues. The new microchip not only has brain-like architecture but also can leverage the high speed and energy efficiency by working on optical energy. This is termed as the silicon photonics revolution in the history of electronics.
As per the scientists, the synapses of human brain outnumber the neurons by ten thousand to one, so they have to replicate the synapses of the human brain.
The scientists are now hoping to start over in creating supercomputers in an optical domain which can think like a human, analyze like a human and store information like a human brain yet faster than a human brain.
